Microchip missed the boat on security and self-programming, imho.

You can only self-program if you are able to do external (normal
programming mode) accesses.

Kind of defeats the purpose, you know.

I would like to be able to update the code in a code-protected chip by
writing, say, a module which only becomes active in a certain situation
(enter a certain password, or pull an input pin low, or some such).  Then I
would be able to keep my code secret and make field updates.

If it had this feature, I would place an order for 20K parts tomorrow (got
the pricing from FAI already).  Now it REALLY is a tough one to call -
maybe I'll go with a Mot 68705P3 which DOES have this ability, sort-of.
